I think you all seem to be taking this waay to far lol. Does it matter what you wear to fly? No, does everyone wearing a uniform look smart? yes, both to people inside and outside the school. I don't think it really matters whether you do or don't, but as a student that has to wear one I just accept it and move on.
And as for spotting people wearing there out of school/airline I do agree, however I'm not going to drive 20mins home to change to drive 20mins back to go to the supermarket I passed on the way home
